Cl. 8-1491Claims ABSTRACT OF THE DISCLOSURE A process for the dyeing of textileribbons wherein the air is swept out of the ribbons and expelled priorto the dye fixing process. The moistened dyed ribbons are delivered to atub which is positionable within a dye fixing chamber, the tub beingheated by a heat source disposed below the tub. A dry vapor is suppliedto the interior of the fixing chamber. The vapors within the fixingchamber are drawn downwardly into the tub and through the ribbonscontained therein, which vapors are drawn through the bottom of the tuband discharged to a location externally of the fixing chamber. The aircontained with the ribbons is also drawn downwardly and dischargedexternally of the dye fixing chamber. The dye fixing chamber is thenheated to a predetermined temperature and maintained at this temperaturefor a predetermined time for fixing of the dye within the textileribbons.

This invention refers to a process for the dyeing of textile ribbons,wherein the air is swept out of the ribbons and expelled prior to thedye fixing process, with the dye then being immediately fixed within theribbons as diS- posed within a dye fixing chamber.

The process preferably initially requires the distribution of theribbons or cables in various units of single multiple yarns which unitsare transported to a device which impregnates them and expresses them bythe dye bath, and is arranged to methodically distribute them equallyinto each of the corresponding integrating compartments of an open tubhaving common bottom and transportable on a carriage running on railsdriven by its own means.

The following phase comprises the longitudinal horizontal displacementof the referred multiple tub to situate same onto the movable carriage,which conveys transversely said tub in front of the entrance mouth ofthe horizontal cylinder of the vaporizer and dye fixer, in whose cavitythe open multiple tub is placed by horizontal rolling displacement; thecylinder cover is then closed to proceed with the primary operation offixing the dye, having previously boiled the water in the bottom of thecylinder and the dry vapor projected by the two lateral parallel tubes;which conjunct whole of ebullition and dry vapor, after heating thecommon base of the tub and the four sidewalls of each of the integratingcompartments, from below upwards, penetrates in the compartments by theupper open part, precisely through the material impregnated with theadequate dye, from above downwards, leaving through a double bottomplaque, perforated, comprising each of the compartments, above which themass of ribbon to be fixed is sustained, to pass the vapor to the commonbottom, sweeping away with same the air contained in the mentioned mass,whose permanence in the material would produce the oxidation of thetextile and which is expelled to the outside of the cylinder owing tothe aspirator suction of a vacuum device situated in the exterior. Theoperation of fixing the dye is then immediately proceeded with, withinthe limits of time and temperature appropriate for the operation to becarried out, after which, the temperature is lowered and the steam inletclosed, the ambient pressure is re-established, the cylinder door isopened, the multiple tub is extracted, sliding same on the transportcarriage, situated in front, to immediately rest it on one of the fixedrear carriages and the dyed material is then removed, extracting samefrom each integral compartment, pulling the perforated plaques of thedouble bottom, while the transport carriage proceeds with the loading ofanother tub, full of material impregnated with the dye stuff to place iton the inside of the vaporizing cylinder, thus initiating another fixingcycle and so on repeatedly.

The first phase of the procedure comprises the situation of the textileribbons up to the wringer-impregnator which is carried out by means of aconventional feeding means, which delivers the ribbons or cables to theguiding cylinder that passes them vertically toward the impregnatorwhere the ribbons are changed from a dry to a moist state due to theabsorption of the dyeing solution.

In the second phase, the moist ribbons are threaded to the upperhorizontal distributor, passing them to the folder device which depositsthem geometrically in the interior of the corresponding compartment thatcomprise the open transportable tub, suspending the ribbons above thedouble bottom perforated plaque. The horizontal folding device comprisesa framework provided with longitudinal reciprocating movement by thesupport of the longitudinal guides of its lower frame, which is providedwith an end V profile to run in the necks of freely gyratory pulleysarranged one at each extremity of the vertical mounts, fixed in thefloor and which form part of the upper framework, above which themultiple open tub is moved, of various compartments, with a doublecommon bottom, which tub, when the compartments are full of the materialto be fixed, is deposited by horizontal longitudinal traction onto thetransport carriage, provided with transversal translatory movement, toconfront with the opening mouth of the vaporizing fixing cylinder, inwhose interior the multiple tub is deposited, full of the material to befixed, or alternatively, removed from its inside when the material isfixed.

The horizontal folding device of the ribbons or of the continuousfilament cables executes the distribution for filling the compartmentsby means of a pair of gyratory cylinders parallel in a longitudinalaxial direction, with a periphery of small bars, provided with aconjoint movement of reciprocated translation in a transverse directiontogether with the gyratory movement of another similar pair ofcylinders, parallel in an axial transverse direction, and animated by areciprocating translation movement impressed by the carriage orframework on the supporting pulleys. The ribbons or cables penetratebetween the virtual hollow of the contact between the four rod cylindersprovided with self movement.

Thus, it is an object of the present invention to provide an improvedprocess for the dyeing of textiled ribbons wherein the air is swept outof the ribbons and expelled prior to the dye fixing process, whichprocess includes the steps of impregnating the ribbons with dyeingpaste, delivering the moistened dyed ribbons to a tub having a ribbonreceiving compartment positioned above a closed chamber with the ribbonreceiving compartment being provided with a perforated bottom wall forseparating the ribbon receiving compartment from the hollow chamber,positioning the tub with the ribbons therein within a dye fixingchamber, heating the tub when positioned within the dye fixing chamber,supplying a dry vapor to the interior of the dye fixing chamber insurrounding relationship to the tub, and creating a partial suctionwithin the closed chamber of the tub for drawing the vapors within thedye fixing chamber and the air contained within the ribbons downwardlythrough the perforated wall of the tub into the closed chamber, and thenpassing the vapor and air to a location external of the dye fixingchamher.

7 To briefly summarize the operation of the present invention, theribbons are deposited into the tub 2, which tub is then positionedwithin the dye fixing chamber defined by the interior of the cylinder 6.The .tub, when positioned within the cylinder 6, is then heated by meansof the boiling water disposed within the bottom of the cylinder 6.Further, a dry vapor is supplied to the interior of the dye fixingchamber through the pipes 60 and orifices 61. Due to the externallypositioned cylinder 69, a suction is imposed on'the opening 64 which isin communication with the chamber 49 provided in the bottom of the tub2- The suction created within the chamber 49 causes the vapors withinthe interior of cylinder 6 to be drawn downwardly through the interiorof the tub and through the perforated wall 50.

The tub containingribbons, as positioned within the cylinder 6, is thenheated to a predetermined temperature and maintained at said temperaturefor a predetermined time to cause fixing of the dye in the textileribbons, whereupon the temperature within the chamber is then loweredand the tub removed from the cylinder 6.
